Supporting Safety in the Lab

Supporting Safety in the Lab

Why are we here?

The purpose of this presentation is to ensure that LSAs are well-prepared to assist in the science lab, particularly with handling Bunsen burners.

By attending this session, you'll gain the knowledge to:

• Safely operate and assist students with Bunsen burners

• Identify potential hazards and prevent accidents

• Know how to respond in case of an emergency

Why is it important?

• Increased vulnerability, e.g. physical, sensory, cognitive

• Ensures inclusion

• Confidence = reassurance

LSU Students

• Prevent accidents

• Promote responsibility

• Protect the equipment

• Supporting the teacher

• Role-modelling safe behaviour
